Jiang An's gloved fingers lightly brushed over the two clumps of decayed tissue, "Although the decay is severe, the lip tissue structure is still discernible."
"Look, this extremely thin part should be the vermillion zone, its edges showing a typical wavy transition."
"And this thicker part is the skin transition area, where you can see the residual stratum corneum structure."
He picked up the tweezers and gently prodded the tissue, "Only human lips have such unique tissue structure characteristics, akin to fingerprints in their identifiability."
Mr. Wang crossed his arms, his eyebrows knitted tightly.
"Can a morphological comparison be conducted? After all, the decay is quite severe..."
"Direct comparison is indeed difficult."
Jiang An nodded, then shifted his tone, "However, we can use the new generation of DNA testing technology to compare the mitochondrial DNA of these lip tissues with Liu Tie's."
